Finding Points of Intersection of Polar-Coordinate Graphs.

Esty, Warren W.

Mathematics Teacher, v84 n6 p472-77 Sep 1991

In polar coordinates, the intersection of the graphs of two functions, f(x) and g(x), does not always correspond to the solutions of the equation f(x) = g(x). Presented are examples to illustrate this concept, proofs demonstrating why this is true, and a computer program to simultaneously plot polar coordinate graphs. (MDH)
